Thread: Handling bytea field in partition trigger function

Handling bytea field in partition trigger function

From

I'm trying to partition a table that has a btyea field used to store pdf data. Basically the procedure filters by date, and creates a new table every month. I'm having problems with the executed sql string that moves the data into the partitioned table from the main insert.

I'm setting

n_document_object bytea := NEW.document_object;

but then the string executed doesn't work. So I'm thinking I need to bind within the function, but I can figure out how. I'm having a hard time finding answers because I'm not exactly sure what I need to ask.

Any help with guidance in what I'm trying to do/ask would be appreciated.

Thank you,
Doug

Look at the "quote_nullable" function and the EXECUTE ... USING syntax:

http://www.postgresql.org/docs/9.0/static/plpgsql-statements.html#PLPGSQL-STATEMENTS-EXECUTING-DYN

If those don't cover your needs, please post the entire function definition and
the exact error message you receive.
